GnuPG is a complete and free implementation of the OpenPGP standard as defined by RFC4880 (also known as PGP).
SaaSHub's Down Detector checks the status of services automatically and regularly. However, we cannot promise 100% accuracy. That is why we depend on user reported issues as well. The WinGPG status here can help you determine if there is a global outage and WinGPG is down for everyone or it is just you that is experiencing problems. Please always report any issues to help others know the current status.
